Suddenly, Pi hears a voice. At first he thinks it's RP. This assumption continues for a number of pages. Then he realizes the voice has a French accent. It's not RP, it's actually another blind castaway on the Pacific.
Their conversation is utterly bizarre. Pi has probably gone mad.
The French castaway tries to eat Pi. The castaway puts his foot into RP's territory and RP, as we know, doesn't take any prisoners.
